// Single source of truth for E2E tests: derive preview-feature data from
// /preview-features.json so we don't have to hand-maintain a parallel array.
//
// Production reads the same JSON via the `@features-manifest` vite alias
// (see `desktop/src/shared/features/manifest.ts`). The localStorage key
// format matches `OVERRIDES_KEY` in `desktop/src/shared/features/store.ts`
// — bumping `version` in `preview-features.json` updates production AND
// every spec automatically.
